Dependence on measurement units of statistical characteristics of time series of realization of the goods

This article deals with the time series of three days volumes of realization of homogeneous goods, presented in various measurement units [in pieces and roubles]. Such statistics as mathematical expectation, quadratic mean deviation, variation, asymmetry and excess are numerically estimated, which characterize the dynamic of behavior of inspected time series. The comparative analysis of these indicators is carried out.
